Colour Rough Texture Synthesis

Original language description

This paper presents an efficient model-based algorithm for realistic modeling of multispectral rough (illumination and view angle dependent) textures. The algorithm starts with range map estimation of the rough texture followed by the spectral and spatial factorization of an input multispectral texture image. Single orthogonal monospectral components are decomposed into a multi-resolution grid and each resolution data factors are independently modeled by their dedicated Gaussian Markov random field model (GMRF). We estimate an optimal contextual neighbourhood and parameters for each GMRF. Single synthesized monospectral texture pyramids are collapsed into the fine resolution images and using the inverseKarhunen-Loeve transformation we obtain the smoothmultispectral texture. Finally both multispectral and range information is combined in a bump filter of the rendering hardware to form the required rough texture.
